How to create new world file

I have an image and don't need to change it.  But I do want to change the projection and then create a new world file.  Is there a way to do this?

  • I forgot to mention that I know how to change the projection, I just don't know how to create a new world file with out creating a new image.

    Load your image, change the projection, then use the procedure to export a new image and note the option to export only the world file. 

    However, most world files don't use the rotation attributes, and the horizontal and vertical scales are normally equal.  That leaves the coordinates of the upper left corner and the x,y scales per pixel as the values used for most images.  Without exporting the image in the new projection, this may not be what you want.  This assumes that we are talking about the same world file:

  • yea, I starting thinking about that farther and realized that the new project may warp the image and then just having a new world file wouldn't work.
